PORTABLE. AUTOMATICALLY-OPERATED OPENING AND CLOSING GATE.

Application filed October 11, 1926, Serial No. 140,752. Renewed March'9, 1929. 7

My invention relates to gates and more particularly to gates whleh canbe opened by passing vehicles and which will be auto matically closedafter the passingof the vehicles; and the object is to provide a gatewhich will be opened by a passing vehicle and which will be pressed downto the ground by the vehicle so that the vehicle will pass throughwithout stopping and which will be restored to the closed position afterthe vehicle passes. Another Ob ect is to provide a gate which isportable so that it can be moved from place to place without having toreconstruct the gate or the means fol mounting or installing the gate.Other objects and advantages will be 'fully (:X- plained in thefollowing description and the invention will be more particularlypointed out in the claim.

Reference is had to the accompanying drawings which form a part of thisapplication.

Fig. 1 is an elevation of a gate which is provided with theimprovements.

Fig. 2 is a detail view of the guide and operating means.

Fig. 3 is an interior elevation, taken substantially on the line 33 ofFig. 1.

Fig. 4 is an elevation of a gate which contains a variation in thestructure.

Similar characters of reference are used to indicate the same partsthroughout the several views.

A frame for a gate way is provided for mounting or installing a gate.This frame has uprights 1 and 2 which are attached to base members 3 and4. A cross bar 5 is attached to the upper ends to brace the up rights 1and 2. Angular braces 6 are also used to brace the uprights 1 and 2.Braces 7 are attached. to the uprights and to the bars 3 and 4. Braces 6are attached to the uprights 1 and 2 and to horizontal basemembers 8.The uprights 1 and 2 may be gained into the members 3 and 4. The gate isprovided with a hinge rod or bar 9 which is iournaled in the uprights 1and 2 near the bottoms thereof. 'The gate is fur-.

ther composed of upright members 11, preferably of pipe, which areconnected to the hinge member 9 by T-joints 12. The

are attached to the members 9 and 13 for the vehicle wheels. The trackmembers 15 may be of sheet metal. Other brace members 16 are attached tothe members 9 and 13.

The gateis held normally in the upright closed position by weights 17and 18 and these weightsv will automatically close the gate after avehicle has passed and opened the gate. Housings 19 are provided for theweights 17 and 18 and these housings serve as guide ways for the weightsin their vertieal motion. The weights 18 are connected to cords orcables 20 which are run upwardly in the housings 19 and over idlepulleys 21 and then down and attached to the top members 13. Springs 22may be used to a form parts of the cables so that there will 'not be toosudden jerking or hammering on the ate when a vehicle comes a ainst thegate. The springs 22 serve as shock absorbers. The weights 17 are sopositioned that the pull 011 the gate will not be impeded by the entireweight of all the weights. Guide rods 23 are provided for the Weights 17and 18 and the weights have openings there through for the guide rods23. Each hoi1sing has a stop shoulder 24 made therein. The weights 17normally rest on the stop shoulders 24, but when the vehicle pushes thegate until the Weights 18 are drawn up:

weights 17 and so lift the weights 17. The effect of such actionwilltend to keep the gate from going downwardly too fast and the combinedweights will help to start the V wardly, they will in time come up underthe frame composed of upright members and a I cross bar attached to saidupright IIIGIHbO/TS, means for hraeing' the lower ends of sald uprights,a gate hingedly connected at its openings therethrough to receive saidguide rods, pulle s suspended from said cross-bar,

and cords attached to said gate and run over said pulleys and down intosaid housings and attached to said. Weights.

In testimony whereof, I set my hand, August, 1926.
